### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary: Creating Iceberg or Paimon external tables with mixed-case
partition columns could fail because Doris converted top-level external column
names to lower case while building external schemas and partition specs.
Reading external table schemas and partition metadata also normalized some
Paimon and Iceberg column names to lower case, so SHOW CREATE and partition
helpers could lose the original external column spelling. This change preserves
the original top-level external field names when converting Doris columns to
Iceberg/Paimon schemas, resolves partition and primary key names
case-insensitively back to the external canonical names, and stops
schema/partition parsing paths from lowercasing external column names.
### Release note
Fix Iceberg and Paimon external table column name casing for mixed-case
partition columns.

- git diff --check
- A broader focused run including two existing Mockito-based
IcebergUtilsTest methods compiled successfully but those two methods failed
locally because Mockito inline Byte Buddy could not self-attach to the Homebrew
JDK 17 VM.
- Behavior changed: Yes. Iceberg and Paimon external schemas, partition
specs, and partition metadata now preserve external column name casing.
- Does this need documentation: No
